Foreword
This is version 2.0.1 of the Linux Standard Base Core Specification for AMD64. An implementation of this version of the specification may not claim to be an implementation of the Linux Standard Base unless it has successfully completed the compliance process as defined by the Free Standards Group.

Introduction
The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification shall include information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one.
This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components may be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in the detail. Information referenced in this way is as much a part of this document as is the information explicitly included here.

I. Introductory Elements

Chapter 1. Scope
1.1. General
The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB.
These specifications are composed of two basic parts: A common specification ("LSB-generic") describing those parts of the interface that remain constant across all implementations of the LSB, and an architecture-specific specification ("LSB-arch") describing the parts of the interface that vary by processor architecture. Together, the LSB-generic and the architecture-specific supplement for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture.
The LSB-generic document shall be used in conjunction with an architecture-specific supplement. Whenever a section of the LSB-generic specification shall be supplemented by architecture-specific information, the LSB-generic document includes a reference to the architecture supplement. Architecture supplements may also contain additional information that is not referenced in the LSB-generic document.
The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation shall provide all of the ABIs listed here. The compilation system may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed.
The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification.
1.2. Module Specific Scope
This is the AMD64 architecture specific Core module of the Linux Standards Base (LSB). This module supplements the generic LSB Core module with those interfaces that differ between architectures.
Interfaces described in this module are mandatory except where explicitly listed otherwise. Core interfaces may be supplemented by other modules; all modules are built upon the core.

Chapter 2. Normative References
The specifications listed below are referenced in whole or in part by the Linux Standard Base. In this specification, where only a particular section of one of these references is identified, then the normative reference is to that section alone, and the rest of the referenced document is informative.

Chapter 3. Requirements
3.1. Relevant Libraries
The libraries listed in Table 3-1 shall be available on x86-64 Linux Standard Base systems, with the specified runtime names. These names override or supplement the names specified in the generic LSB specification. The specified program interpreter, referred to as proginterp in this table, shall be used to load the shared libraries specified by DT_NEEDED entries at run time.
Table 3-1. Standard Library Names
Library	Runtime Name	
proginterp	/lib64/ld-lsb-x86-64.so.2	
libc	libc.so.6	
libcrypt	libcrypt.so.1	
libdl	libdl.so.2	
libm	libm.so.6	
libpthread	libpthread.so.0	
libgcc_s	libgcc_s.so.1	
libz	libz.so.1	
libncurses	libncurses.so.5	
libutil	libutil.so.1	

These libraries will be in an implementation-defined directory which the dynamic linker shall search by default.
3.2. LSB Implementation Conformance
A conforming implementation shall satisfy the following requirements:
•	The implementation shall implement fully the architecture described in the hardware manual for the target processor architecture.
•	The implementation shall be capable of executing compiled applications having the format and using the system interfaces described in this document.
•	The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces shall behave as specified in this document.
•	The map of virtual memory provided by the implementation shall conform to the requirements of this document.
•	The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such activities shall conform to the formats described in this document.
•	The implementation shall provide all of the mandatory interfaces in their entirety.
•	The implementation may provide one or more of the optional interfaces. Each optional interface that is provided shall be provided in its entirety. The product documentation shall state which optional interfaces are provided.
•	The implementation shall provide all files and utilities specified as part of this document in the format defined here and in other referenced documents. All commands and utilities shall behave as required by this document. The implementation shall also provide all mandatory components of an application's runtime environment that are included or referenced in this document.
•	The implementation, when provided with standard data formats and values at a named interface, shall provide the behavior defined for those values and data formats at that interface. However, a conforming implementation may consist of components which are separately packaged and/or sold. For example, a vendor of a conforming implementation might sell the hardware, operating system, and windowing system as separately packaged items.
•	The implementation may provide additional interfaces with different names. It may also provide additional behavior corresponding to data values outside the standard ranges, for standard named interfaces.
3.3. LSB Application Conformance
A conforming application shall satisfy the following requirements:
•	Its executable files are either shell scripts or object files in the format defined for the Object File Format system interface.
•	Its object files participate in dynamic linking as defined in the Program Loading and Linking System interface.
•	It employs only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as being for use by applications.
•	If it requires any optional interface defined in this document in order to be installed or to execute successfully, the requirement for that optional interface is stated in the application's documentation.
•	It does not use any interface or data format that is not required to be provided by a conforming implementation, unless: 
•	If such an interface or data format is supplied by another application through direct invocation of that application during execution, that application is in turn an LSB conforming application.
•	The use of that interface or data format, as well as its source, is identified in the documentation of the application.
•	It shall not use any values for a named interface that are reserved for vendor extensions.
A strictly conforming application does not require or use any interface, facility, or implementation-defined extension that is not defined in this document in order to be installed or to execute successfully.

Chapter 4. Definitions

Chapter 5. Terminology
For the purposes of this document, the following terms apply:
archLSB
 	The architectural part of the LSB Specification which describes the specific parts of the interface that are platform specific. The archLSB is complementary to the gLSB.
Binary Standard
 	The total set of interfaces that are available to be used in the compiled binary code of a conforming application.
gLSB
 	The common part of the LSB Specification that describes those parts of the interface that remain constant across all hardware implementations of the LSB.
implementation-defined
 	Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be portable across conforming implementations. The implementor shall document such a value or behavior so that it can be used correctly by an application.
Shell Script
 	A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its interpreter binary.
Source Standard
 	The set of interfaces that are available to be used in the source code of a conforming application.
undefined
 	Describes the nature of a value or behavior not defined by this document which results from use of an invalid program construct or invalid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
unspecified
 	Describes the nature of a value or behavior not specified by this document which results from use of a valid program construct or valid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations.
Other terms and definitions used in this document shall have the same meaning as defined in Chapter 3 of the Base Definitions volume of ISO POSIX (2003).

Chapter 6. Documentation Conventions
Throughout this document, the following typographic conventions are used: 
function()
 	the name of a function
command
 	the name of a command or utility
CONSTANT
 	a constant value
parameter
 	a parameter
variable
 	a variable
Throughout this specification, several tables of interfaces are presented. Each entry in these tables has the following format: 
name
 	the name of the interface
(symver)
 	An optional symbol version identifier, if required.
[refno]
 	A reference number indexing the table of referenced specifications that follows this table.
For example, 
forkpty(GLIBC_2.0) [1]	

refers to the interface named forkpty with symbol version GLIBC_2.0 that is defined in the first of the listed references below the table.

I. Base Libraries

Chapter 1. Libraries
An LSB-conforming implementation shall support some base libraries which provide interfaces for accessing the operating system, processor and other hardware in the system.
Interfaces that are unique to the AMD64 platform are defined here. This section should be used in conjunction with the corresponding section in the Linux Standard Base Specification.
1.1. Program Interpreter/Dynamic Linker
The LSB specifies the Program Interpreter to be /lib64/ld-lsb-x86-64.so.2.
1.2. Interfaces for libc
Table 1-1 defines the library name and shared object name for the libc library
Table 1-1. libc Definition
Library:	libc	
SONAME:	libc.so.6	

The behavior of the interfaces in this library is specified by the following specifications:
Large File Support

1.3. Data Definitions for libc
This section defines global identifiers and their values that are associated with interfaces contained in libc. These definitions are organized into groups that correspond to system headers. This convention is used as a convenience for the reader, and does not imply the existence of these headers, or their content.
These definitions are intended to supplement those provided in the referenced underlying specifications.
This specification uses ISO/IEC 9899 C Language as the reference programming language, and data definitions are specified in ISO C format. The C language is used here as a convenient notation. Using a C language description of these data objects does not preclude their use by other programming languages.

Other interfaces listed above for libgcc_s shall behave as described in the referenced base document.
_Unwind_DeleteException
Name
_Unwind_DeleteException — private C++ error handling method
Synopsis
void _Unwind_DeleteException((struct _Unwind_Exception *object));
Description
_Unwind_DeleteException deletes the given exception object. If a given runtime resumes normal execution after catching a foreign exception, it will not know how to delete that exception. Such an exception shall be deleted by calling _Unwind_DeleteException. This is a convenience function that calls the function pointed to by the exception_cleanup field of the exception header.
_Unwind_Find_FDE
Name
_Unwind_Find_FDE — private C++ error handling method
Synopsis
fde * _Unwind_Find_FDE(void *pc, (struct dwarf_eh_bases *bases));
Description
_Unwind_Find_FDE looks for the object containing pc, then inserts into bases.
_Unwind_ForcedUnwind
Name
_Unwind_ForcedUnwind — private C++ error handling method
Synopsis
_Unwind_Reason_Code _Unwind_ForcedUnwind((struct _Unwind_Exception *object), _Unwind_Stop_Fn stop, void *stop_parameter);
Description
_Unwind_ForcedUnwind raises an exception for forced unwinding, passing along the given exception object, which should have its exception_class and exception_cleanup fields set. The exception object has been allocated by the language-specific runtime, and has a language-specific format, except that it shall contain an _Unwind_Exception struct.
Forced unwinding is a single-phase process. stop and stop_parameter control the termination of the unwind process instead of the usual personality routine query. stop is called for each unwind frame, with the parameteres described for the usual personality routine below, plus an additional stop_parameter.
Return Value
When stop identifies the destination frame, it transfers control to the user code as appropriate without returning, normally after calling _Unwind_DeleteException. If not, then it should return an _Unwind_Reason_Code value.
If stop returns any reason code other than _URC_NO_REASON, then the stack state is indeterminate from the point of view of the caller of _Unwind_ForcedUnwind. Rather than attempt to return, therefore, the unwind library should use the exception_cleanup entry in the exception, and then call abort.
_URC_NO_REASON
 	This is not the destination from. The unwind runtime will call frame's personality routine with the _UA_FORCE_UNWIND and _UA_CLEANUP_PHASE flag set in actions, and then unwind to the next frame and call the stop function again.
_URC_END_OF_STACK
 	In order to allow _Unwind_ForcedUnwind to perform special processing when it reaches the end of the stack, the unwind runtime will call it after the last frame is rejected, with a NULL stack pointer in the context, and the stop function shall catch this condition. It may return this code if it cannot handle end-of-stack.
_URC_FATAL_PHASE2_ERROR
 	The stop function may return this code for other fatal conditions like stack corruption.
_Unwind_GetDataRelBase
Name
_Unwind_GetDataRelBase — private IA64 C++ error handling method
Synopsis
_Unwind_Ptr _Unwind_GetDataRelBase((struct _Unwind_Context *context));
Description
_Unwind_GetDataRelBase returns the global pointer in register one for context.
_Unwind_GetGR
Name
_Unwind_GetGR — private C++ error handling method
Synopsis
_Unwind_Word _Unwind_GetGR((struct _Unwind_Context *context), int index);
Description
_Unwind_GetGR returns data at index found in context. The register is identified by its index: 0 to 31 are for the fixed registers, and 32 to 127 are for the stacked registers.
During the two phases of unwinding, only GR1 has a guaranteed value, which is the global pointer of the frame referenced by the unwind context. If the register has its NAT bit set, the behavior is unspecified.
_Unwind_GetIP
Name
_Unwind_GetIP — private C++ error handling method
Synopsis
_Unwind_Ptr _Unwind_GetIP((struct _Unwind_Context *context));
Description
_Unwind_GetIP returns the instruction pointer value for the routine identified by the unwind context.
_Unwind_GetLanguageSpecificData
Name
_Unwind_GetLanguageSpecificData — private C++ error handling method
Synopsis
_Unwind_Ptr _Unwind_GetLanguageSpecificData((struct _Unwind_Context *context), uint value);
Description
_Unwind_GetLanguageSpecificData returns the address of the language specific data area for the current stack frame.
_Unwind_GetRegionStart
Name
_Unwind_GetRegionStart — private C++ error handling method
Synopsis
_Unwind_Ptr _Unwind_GetRegionStart((struct _Unwind_Context *context));
Description
_Unwind_GetRegionStart routine returns the address (i.e., 0) of the beginning of the procedure or code fragment described by the current unwind descriptor block.
_Unwind_GetTextRelBase
Name
_Unwind_GetTextRelBase — private IA64 C++ error handling method
Synopsis
_Unwind_Ptr _Unwind_GetTextRelBase((struct _Unwind_Context *context));
Description
_Unwind_GetTextRelBase calls the abort method, then returns.
_Unwind_RaiseException
Name
_Unwind_RaiseException — private C++ error handling method
Synopsis
_Unwind_Reason_Code _Unwind_RaiseException((struct _Unwind_Exception *object));
Description
_Unwind_RaiseException raises an exception, passing along the given exception object, which should have its exception_class and exception_cleanup fields set. The exception object has been allocated by the language-specific runtime, and has a language-specific format, exception that it shall contain an _Unwind_Exception.
Return Value
_Unwind_RaiseException does not return unless an error condition is found. If an error condition occurs, an _Unwind_Reason_Code is returnd:
_URC_END_OF_STACK
 	The unwinder encountered the end of the stack during phase one without finding a handler. The unwind runtime will not have modified the stack. The C++ runtime will normally call uncaught_exception in this case.
_URC_FATAL_PHASE1_ERROR
 	The unwinder encountered an unexpected error during phase one, because of something like stack corruption. The unwind runtime will not have modified the stack. The C++ runtime will normally call terminate in this case.
_URC_FATAL_PHASE2_ERROR
 	The unwinder encountered an unexpected error during phase two. This is usually a throw, which will call terminate.
_Unwind_Resume
Name
_Unwind_Resume — private C++ error handling method
Synopsis
void _Unwind_Resume((struct _Unwind_Exception *object));
Description
_Unwind_Resume resumes propagation of an existing exception object. A call to this routine is inserted as the end of a landing pad that performs cleanup, but does not resume normal execution. It causes unwinding to proceed further.
_Unwind_SetGR
Name
_Unwind_SetGR — private C++ error handling method
Synopsis
void _Unwind_SetGR((struct _Unwind_Context *context), int index, uint value);
Description
_Unwind_SetGR sets the value of the register indexed for the routine identified by the unwind context.
_Unwind_SetIP
Name
_Unwind_SetIP — private C++ error handling method
Synopsis
void _Unwind_SetIP((struct _Unwind_Context *context), uint value);
Description
_Unwind_SetIP sets the value of the instruction pointer for the routine identified by the unwind context

Appendix A. GNU Free Documentation License
Version 1.1, March 2000
Copyright (C) 2000 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
A.1. PREAMBLE
The purpose of this License is to make a manual, textbook, or other written document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.
This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.
A.2. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you".
A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.
A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (For example, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.
The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License.
The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License.
A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, whose contents can be viewed and edited directly and straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup has been designed to thwart or discourage subsequent modification by readers is not Transparent. A copy that is not "Transparent" is called "Opaque".
Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML designed for human modification. Opaque formats include PostScript, PDF, proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML produced by some word processors for output purposes only.
The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.
A.3. VERBATIM COPYING
You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.
You may also lend copies, under the same conditions stated above, and you may publicly display copies.
A.4. COPYING IN QUANTITY
If you publish printed copies of the Document numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a publicly-accessible computer-network location containing a complete Transparent copy of the Document, free of added material, which the general network-using public has access to download anonymously at no charge using public-standard network protocols. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.
A.5. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:
	A.	Use in the Title Page  (and on the covers, if any) a title distinct from that of the  Document, and from those of previous versions (which should, if  there were any, be listed in the History section of the  Document). You may use the same title as a previous version if  the original publisher of that version gives permission.
	B.	List on the Title Page,  as authors, one or more persons or entities responsible for  authorship of the modifications in the Modified Version,  together with at least five of the principal authors of the  Document (all of its principal authors, if it has less than  five).
	C.	State on the Title page  the name of the publisher of the Modified Version, as the  publisher.
	D.	Preserve all the  copyright notices of the Document.
	E.	Add an appropriate  copyright notice for your modifications adjacent to the other  copyright notices.
	F.	Include, immediately  after the copyright notices, a license notice giving the public  permission to use the Modified Version under the terms of this  License, in the form shown in the Addendum below.
	G.	Preserve in that license  notice the full lists of Invariant Sections and required Cover  Texts given in the Document's license notice.
	H.	Include an unaltered  copy of this License.
	I.	Preserve the section  entitled "History", and its title, and add to it an item stating  at least the title, year, new authors, and publisher of the  Modified Version as given on the Title Page. If there is no  section entitled "History" in the Document, create one stating  the title, year, authors, and publisher of the Document as given  on its Title Page, then add an item describing the Modified  Version as stated in the previous sentence.
	J.	Preserve the network  location, if any, given in the Document for public access to a  Transparent copy of the Document, and likewise the network  locations given in the Document for previous versions it was  based on. These may be placed in the "History" section. You  may omit a network location for a work that was published at  least four years before the Document itself, or if the original  publisher of the version it refers to gives permission.
	K.	In any section entitled  "Acknowledgements" or "Dedications", preserve the section's  title, and preserve in the section all the substance and tone of  each of the contributor acknowledgements and/or dedications  given therein.
	L.	Preserve all the  Invariant Sections of the Document, unaltered in their text and  in their titles. Section numbers or the equivalent are not  considered part of the section titles.
	M.	Delete any section  entitled "Endorsements". Such a section may not be included in  the Modified Version.
	N.	Do not retitle any  existing section as "Endorsements" or to conflict in title with  any Invariant Section.
If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.
You may add a section entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.
The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.
A.6. COMBINING DOCUMENTS
You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice.
The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.
In the combination, you must combine any sections entitled "History" in the various original documents, forming one section entitled "History"; likewise combine any sections entitled "Acknowledgements", and any sections entitled "Dedications". You must delete all sections entitled "Endorsements."
A.7. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.
A.8. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, does not as a whole count as a Modified Version of the Document, provided no compilation copyright is claimed for the compilation. Such a compilation is called an "aggregate", and this License does not apply to the other self-contained works thus compiled with the Document, on account of their being thus compiled, if they are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one quarter of the entire aggregate, the Document's Cover Texts may be placed on covers that surround only the Document within the aggregate. Otherwise they must appear on covers around the whole aggregate.
A.9. TRANSLATION
Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License provided that you also include the original English version of this License. In case of a disagreement between the translation and the original English version of this License, the original English version will prevail.
A.10. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except as expressly provided for under this License. Any other attempt to copy, modify, sublicense or distribute the Document is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
A.11. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation.
A.12. How to use this License for your documents
To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:
Copyright (c) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation; with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. A copy of the license is included in the section entitled "GNU Free Documentation License".
If you have no Invariant Sections, write "with no Invariant Sections" instead of saying which ones are invariant. If you have no Front-Cover Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
